Cow’s milk Kefir – Original

No. Kefir is alive and keeps fermenting in the bottle; the yeasts make the bubbles, and no carbon dioxide is added. It is fizzier in hot weather or right after delivery. Chill it well first, keep it upright at the back of the fridge (not in the door), and never shake a sealed bottle. Open it slowly over the sink; if it starts to foam, close it again, wait for the foam to settle and release the gas in a few steps. Once the gas is out, close it and tilt gently to mix.

Unopened and refrigerated, the original keeps 21 days and fruit flavors 14 days; the date is on the cap. It tastes best in the first 7 days and gets more tart and fizzy after that. Finish within 3 days of opening.

Refrigerate it right away. Warmth speeds up fermentation: more tart, separated, fizzier, a more swollen bottle. If it was left out for long, or smells off, shows mould, changes colour or leaks, do not drink it; send photos to LINE @642sgfta. If nobody is home in the day, choose Black Cat 7-ELEVEN chilled pickup.

Yes. It is fermented naturally with kefir grains and no thickener, so texture varies with temperature from batch to batch. Fresh kefir is runnier and becomes thicker and tarter after a few days in the fridge. A layer of whey is natural too; tilt gently to mix before drinking.

Kefir fermented with grains is naturally tart. Add a little honey, jam or fresh fruit, stir it into oats, or blend it with banana into a smoothie. Start with a small glass and get used to it.

No. The sugar on the label (2.5 g per 100 g) is lactose from the milk itself; no sugar, sweetener or substitute is added. Fruit flavors contain natural fruit jam with a little sugar.

Children over one year old with no special dietary restrictions can drink it; start with a small spoonful. If you are pregnant, lactose intolerant, have a chronic condition or are in treatment, ask your doctor first. It contains milk and is not suitable for people with a milk allergy; if you don’t drink cow’s milk, try soy milk kefir (lacto-vegetarian) or water kefir (vegan).

Start with about 50 g, then a glass a day (about 100–250 g) once you are used to it, in one go or split morning and evening, before or after meals. If you feel bloated, have less or skip a day.

Freezing is not recommended: the bottle can deform and the texture changes after thawing. Keep it at 2–4°C. Do not microwave or steam it; for a less cold glass, leave it out briefly or warm it gently in a water bath.

Kefir is fermented with live kefir grains that hold many lactic acid bacteria and yeasts, which is why it is gently tart and lightly fizzy. Its texture sits between drinking yogurt and yogurt: drink it, stir it into oats, or strain it into Greek yogurt.

Yes. At checkout choose Black Cat 7-ELEVEN chilled pickup and pick a store near you. You get an SMS when it arrives, kept cold; please collect it soon. Cash on delivery is available.

No. It is made with pasteurized whole fresh milk fermented with kefir grains, and the grains are strained out afterwards. To make kefir at home, buy our live kefir grains.

Milk kefir is fresh, chilled food, so the 7-day cooling-off period does not apply. If it arrives defective, wrong or damaged, send photos of the parcel and product to LINE @642sgfta within 72 hours; we will resend or refund and cover the shipping.

Kefir is a food, not a medicine. Please see a doctor first if you feel unwell.
